Where Did Lorence Wenke’s Votes Come From?

The closest state legislative race in Michigan in 2014 was in state senate district 20, which is coterminous with Kalamazoo County. The district was vacated by Republican senator Tonya Schuitmaker, who ran for reelection in a neighboring district due to redistricting.

The Republican candidate was 61st district state rep Margaret O’Brien of Portage. The democrat candidate was 60th district state rep Sean McCann of Kalamazoo. Both are fairly typical representatives of their parties.

Aside from the closeness of the race, there was another complicating factor. Former state rep Lorence Wenke ran as a Libertarian after having originally filed to run in the Republican primary. Wenke was a moderate Republican state rep 2002-2008. He had an eclectic platform emphasizing support for gay rights and support for cutting government employee benefits. In the course of the campaign, he announced support for several tax increases and other un-libertarian policies.

The election results, after a recount, were

O’Brien 36645 (45.6%)
McCann 36584 (45.5%)
Wenke 7171 (8.9%)

The following map shows the average Republican performance by precinct for five 2014 election (Governor, SOS, AG, US Senate, US House). Each darker shade of red represents a 5% PVI range. (For example, the darkest shade of red represents precincts 15-20% more Republican than the county as a whole.) Each darker shade of blue represents a 5% PVI range, except that black represents 35-50% more democrat than the county as a whole.

The city of Kalamazoo is heavily democrat, with minority areas particularly so. The most Republican areas are rural townships and some upscale lake areas. Among closer suburbs, Portage leans Republican and Oshtemo and Comstock are close to even.

Here is a map of the results in the state senate race by precinct.

Superficially, the results appear very similar to the other countywide elections.

We can measure candidates’ performance in precincts relative to the GOP average and their overall performance. Break down the precincts into four categories relative to the partisan average:

less than 95% (orange)
95-100% (yellow)
100-105% (light green)
more than 105% (green)

Here is O’Brien’s relative performance.

O’Brien overperfomed in Alamo, Brady, Charleston, Climax, Prairie Ronde, Texas, Wakeshma, and Portage

Here is McCann’s relative performance.

McCann overperfomed in the city of Kalamazoo and Kalamazoo Township.

Where did Wenke do best? His top precinct was the city of Galesburg (18.8%). Most of Wenke’s top precincts are in his old district (the eastern half of the county).

Wenke got 11.6% in the 63rd state house district.
Wenke got 8.4% in the 61st district.
Wenke got 7.6% in the 60th district.
Wenke got 9.1% in the 66th district.

Break his precincts in four categories:
less than 7% (orange)
7-9% (yellow)
9-11% (light green)
more than 11% (dark green)

The narrow result naturally raises the question of what effect Wenke had on the election. Short of asking all of Wenke’s voters, we can’t know for sure who they would have supported in a two-way race.

The conventional wisdom is that Wenke took votes from O’Brien. This is because Wenke used to be a Republican, he represented a mostly Republican area, and libertarians are usually closer to Republicans on the issues.

I examined the results precinct-by-precinct to see what could be learned. I calculated a GOP average by precinct based on the other five countywide races. Scaling this by the total votes O’Brien and McCann received, I projected how their votes should have been distributed. I compared this with Wenke’s performance in each precinct.

Consider Galesburg, Wenke’s top precinct (18.8%). O’Brien got 99.7% of her projected total. McCann got 85.9% of his projected total. This strongly implies that Wenke’s voters would have supported McCann.

There were 20 precincts where Wenke got more than 11%. O’Brien overperformed in 6 of them and underperformed in 12 of them (2 with less than 95% of her projected total.) McCann overperformed in 1 of them and underperformed in 19 of them (12 with less than 95% of his projected total.)

There were 20 precincts where Wenke got less than 7%. O’Brien overperformed in 7 of them and underperformed in 13 of them (9 with less than 95% of her projected total.) McCann overperformed in 18 of them (8 with more than 105% of his projected total.) and underperformed in 2 of them.

McCann underperformed in most precincts where Wenke got more than 11%, and overperformed in most precincts where Wenke got less than 7%. The same is not true for O’Brien. This strongly implies that Wenke took significantly more votes from McCann. Since O’Brien won by only 61 votes, Wenke cost McCann the election. Wenke appears to have done best with democrats in his former state house district.

Wenke absolute performance versus McCann relative performance

An analysis by Gongwer reached the same conclusion using poor reasoning. They correctly noted that McCann did worse than democrat state house candidates. But this does not prove that Wenke’s votes came from McCann, since he could just have been a weaker candidate (or O’Brien stronger). Using different races in different parts of the county is bad methodology, especially when two (60, 63) were uncompetitive and one (61) had a substantial Libertarian vote.

In the 61st state house district, the results were 48.4% Iden, 42.7% Fisher, 8.9% Stampfler. Notably, the correlation between Wenke and Stampfler in the 61st was only r=.032, implying that their supporters voted for them as individuals, not libertarians.

    I thought the Dems underperformed across the state for the most part. There were some aberrations, and a couple of close races, but the Dem coattails never materialized.

    An amazing thing given the utter failure of the Land campaign.

      Why? Snyder bled out a -267,435 votes in all 83 counties in 2014. There were only 69,557 less voters in 2014 than in 2010. Not sure what tea leafs you read, Hoss.

      As for the rest of CF's bullshit, check Schuitmaker's vote record - she's Richardville with an official gash. O’Brien? Equally douchetastic on many levels. Ya, Jack should've never endorsed her.

      Libertarians aren't all about Pride flags, jokesmoke, and a little abortion is okie dokie? Since when.
